For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
Hydrogen is smaller in size compared to other elements in Group 1 because it has only one electron and a smaller atomic radius than the rest of the elements in that group.
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
Group-1 has largest atomic radius. It decreases across a period
It tends to increaseThe atomic radius increases down the group
The atomic radius of argon is smaller than the atomic radius of krypton. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of extra electron shells. Argon is located above krypton in the periodic table, so it has a smaller atomic radius.
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
Yes, carbon has a smaller atomic radius than germanium. This is because, as you move down a group on the periodic table, atomic radius generally increases due to the addition of more electron shells. Germanium is below carbon in the same group, so it has a larger atomic radius.
The element in group 1 with the smallest atomic radius is lithium, due to its higher nuclear charge compared to the other elements in the group (such as sodium and potassium). This higher nuclear charge attracts the electrons more strongly, leading to a smaller atomic radius.
Francium has a larger atomic radius than sodium. Francium is located in the last group of the periodic table, so it has more electron shells than sodium, which results in a larger atomic radius.
Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.
Hydrogen is smaller in size compared to other elements in Group 1 because it has only one electron and a smaller atomic radius than the rest of the elements in that group.
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
